Today Marvel Studios released a 15-second video teaser for its upcoming film Guardians of the Galaxy. A full trailer is scheduled to be released during tonight's episode of Jimmy Kimmel Live. The clip is the first look at a number of characters, including Star Lord (Chris Pratt), Gamora (Zoe Saldana), Groot (voiced by Vin Diesel), and Korath (Djimon Hounsou). If none of these names sound familiar, don't worry. Although the Guardians have been around in one form or another for the past 45 years, they are one of Marvel Comics' underused properties and considered to have more of a cult following, especially in comparison to the top-tier heroes featured in The Avengers.

Guardians is actor Chris Pratt's first live-action leading role, following his turn as the voice of Emmet in The Lego Movie. Last summer the Parks and Recreation star shared photos of his newly muscular body, developed in preparation for this film. Pratt is matched with athletic costars including wrestler Dave Bautista, who portrays Drax the Destroyer and, if the comics are any indication, will appear shirtless through much of the film.
